This work describes the participation of the Universidad Austral de Chile (UACh) in the experimental network M6Bone or IPv6 multicast network. Currently the M6Bone network works in distributed manner, giving support to connections at global scale. Its administration is coordinated from the French research and development network RENATER. Many research projects make use of this worldwide network structure, using it as a great test laboratory with the intention to enable and accelerate the migration of IPv4 to IPv6. In the implementation of the model, free software was used to configure an IPv6 router with multicast support and videoconference tools were used to verify the correct operation. It could be verified that the connection mechanism enables video and audio conferencing of good quality on global scale. Therefore, the use of IPv6 for applications of this type can be promoted.
